Escaping by default -- possible without editing the lib?

I'm looking into a number of HTML templating libraries, and so far they all have
the downside of providing no way to escape all data for HTML by *default*.

In the case of FreeMarker, I'm aware of the <#escape as> directive, but the
developer has to remember to include that on every page! This makes me a bit
uneasy -- just like having to remember to put charset=UTF-8 on every page
instead of instructing the server to always add that header.

Other than hacking on the jar, is there a way to ensure that the default is to
escape all ${data} as HTML?
